Abstract
The invention concerns biologically degradable polyester amides P1 obtainable through reaction of a mixture consisting essentially of the following: (a1) a mixture consisting essentially of: 35-95 mol percent adipic acid or ester-forming derivatives thereof or mixtures thereof, 5-65 mol percent terephthalic acid or ester-forming derivatives thereof or mixtures thereof, and 0-5 mol percent a compound containing sulphonate groups (the sum of the individual molar percentages is 100); (a2) a mixture consisting essentially of: (a21) 99.5-0.5 mol percent a dihydroxy compound chosen from the group comprising C2-C6 alkane diols and C5-C10 cycloalkane diols, (a22) 0.5-99.5 mol percent an amino C2-C12 alkanol or an amino-C5-C10 cycloalkanol, (a23) 0-50 mol percent a diamino C1-C8 alkane; and (a24) 0-50 mol percent a 2,2`-bisoxazoline of general formula (I), in which R1 is a single bond, a (CH2)q-alkylene group in which q = 2, 3 or 4, or a phenylene group (the sum of the individual molar percentages is 100 and the molar ratio of a1 to a2 is in the range 0.4:1 - 1.5:1). The polyester amides P1 will have a molecular weight (Mn) in the range 4000-40,000 g/mol, a viscosity number in the range 30-350 g/ml (measured in o-dichlorobenzene/phenol (weight ratio 50/50) at a concentration of 0.5 wt.percent polyester amide P1 at a temperature of 25 degree C) and a melting point in the range 50-220 degree C; and a quantity of a compound D equivalent to 0-5 mol percent of the molar quantity of components (a1) must also be used for the production of the polyester amides P1, said compound D having at least three groups capable of ester formation. The invention also concerns other biologically degradable polymers and thermoplastic moulding materials, processes for manufacturing the same, the use thereof for producing biologically degradable moulded articles and adhesives, and biologically degradable moulded articles, foams and blends with starch which can be obtained from the polymers or moulding materials according to the invention.
